A Comparison of Different Methodologies for PVB Interlayer Modulus Characterization

The proper measurement and interpretation of modulus data for glass laminate interlayers can be quite complex. The development of master curves using different deformation modes and the preparation of the samples for measurement can significantly affect the results. International standard ISO 6721,...
